  • Publication number: 20250178486
    Abstract: A vehicle includes a chassis, a body, and a door assembly. The body is supported by the chassis, and defines a driver compartment and a cargo compartment. The driver compartment has a cab opening and the cargo compartment has a cargo opening. The door assembly is coupled to the body and provides selective access into the driver compartment and into the cargo compartment through the cab opening and cargo opening, respectively. The door assembly includes a first door and a second door. The first door is movable between a first position extending across the cab opening and a second position extending at least partially across a portion of the cab opening. The second door is movable between a third position extending across the cargo opening and a fourth position extending at least partially across a portion of the cab opening.

  • Publication number: 20250050714
    Abstract: A door includes an inner wall, an outer wall, and a window assembly including a window. The inner wall is configured to engage with a cab of a vehicle. The outer wall is coupled to the inner wall and spaced apart from the inner wall to form an interior cavity. The door is configured to move between a closed position in which the inner wall is engaged with the cab and an open position in which the inner wall is separated from the cab. In the closed position, at least a portion of the interior cavity is configured to be disposed outboard from the cab in a lateral direction. The window is slidably engaged to the door and configured to move between an extended position and a retracted position. In the retracted position, the window is at least partially disposed in the portion of the interior cavity.
